Lanthanum hydroxide is white powder, which is rare earth hydroxide. It is hard to dissolve in water and tend to absorb CO2 from air. It decompose when heating not reach melting point. Decomposition temperature is 260℃. LaH3O3 is stable at room temperature and pressure, which dissolve in acids, but not water. Lanthanum oxide is the raw material.
